You can use crimp connectors on the diode leads or solder them. Then, cover the diode with 2 laters of heat shrink tubing.

If desired, an "idiot light" with a # 194 lamp, or equivalent is a direct substitute for the diode.

My picture is generic... the large output lead needs to get to the ammeter. You can splice it to the wire NOW attached to the "BATT" terminal on the voltage regulator, or you can run the new wire all the way to the ammeter.

The existing wires that will not longer be used can be taped up and out of the way.

If the full-sized alternator is physically too large, some guys are using Hitachi alternators, which connect up in a similar manner.

Bracket "mods" will be needed, the pulley on the exixting Delco generator will swap to the alternator, if desired, to match the width of the existing pulleys/belt.

This setup, using a standard "3-wire" alternator will "excite" (begin to charge) at a lower engine RPM than the (goofy) one-wire alternators often sold for these conversions.
